48V Telecom-Grade LiFePO4 Rack Battery
1. Industry-Leading Safety & Global Certifications
Engineered for mission-critical environments, our battery meets the world’s most stringent safety standards, including UL1973, IEC62619, CE, and UN38.3. With a Class 9 hazardous material rating, it ensures maximum protection for both residential and industrial installations.
2. Ultra-Long Lifespan (6000+ Cycles)
Designed for longevity, this LiFePO4 system delivers over 6,000 deep discharge cycles. Even with daily use, the battery provides a reliable service life of 10–15 years, significantly lowering the Total Cost of Ownership (TCO) compared to lead-acid alternatives.
3. 1C Rapid Charging Technology
Minimize downtime with high-efficiency performance. Our telecom-grade cells support 1C fast charging, allowing the system to reach a full state of charge in approximately 1.5 hours—ideal for areas with unstable grids or high-demand solar applications.
4. Intelligent Smart BMS Protection
The integrated Smart Battery Management System (BMS) acts as the brain of the unit. It provides real-time monitoring, precision cell balancing, and multi-layer protection against over-voltage, over-current, and thermal runaway.
5. Modular & Scalable "Plug-and-Play" Design
Future-proof your energy needs. The compact, space-saving rackmount form factor allows for easy parallel expansion. Whether starting small or building a large-scale energy bank, the modular design adapts to your specific capacity requirements.
6. Lightweight & Easy Installation
Weighing as little as 24.4kg, this battery is significantly lighter than traditional storage options. The standardized rackmount dimensions allow for quick integration into existing server cabinets, reducing labor costs and installation complexity.
